As a specialized manufacturer established in 2014, Henan San Kuang Machinery Technology operates from a substantial facility in Luoyang, China, dedicated to producing high-performance bearing solutions. Our Self-Aligning Ball Bearings, crafted from robust carbon steel and featuring a convenient lubrication port, are engineered to deliver reliable operation and extended service life in demanding applications. We combine rigorous manufacturing standards with a commitment to providing a comprehensive warranty, offering our global partners a dependable component that reduces maintenance downtime and enhances equipment longevity.
This product is designed to address common challenges in machinery where misalignment or shaft deflection occurs. Its core value lies in its ability to maintain smooth rotation and load distribution even under imperfect mounting conditions, thereby protecting connected components from stress and wear.
Key Features & Technical Specifications:
- Self-Aligning Design: The internal ball and raceway geometry allows the bearing to adjust to minor angular misalignments between the shaft and housing. This feature is crucial for applications where perfect alignment is difficult to maintain or where shaft deflection is expected under load.
- Carbon Steel Construction: The bearing rings and balls are manufactured from selected carbon steel, providing a balance of strength, hardness, and cost-effectiveness suitable for a wide range of industrial environments.
- Integrated Lubrication Port: A dedicated port facilitates easy re-lubrication. This allows for maintenance intervals to be extended, ensures consistent lubrication film quality, and can significantly prolong bearing life compared to sealed-for-life units in harsh conditions.
-
Performance Advantages: The combination of materials and design translates into several tangible benefits for the end-user:
- Reduced Vibration & Noise: Proper alignment minimizes uneven loading and rolling element skidding, leading to smoother, quieter operation.
- Lower Maintenance Costs: The self-aligning capability can reduce the frequency of alignment checks and corrections. The lubrication port simplifies maintenance tasks.
- Enhanced System Reliability: By accommodating misalignment, the bearing protects other components in the drive train from excessive forces, reducing the risk of cascade failures.
Typical Configurations & Parameters:
While specific dimensions and load ratings are customizable based on your requirements, the following table outlines common parameters associated with this product line:
| Parameter | Description / Typical Range |
| Inner Diameter (d) | Customizable from small to medium industrial sizes |
| Outer Diameter (D) | Corresponds to standard housing bore sizes |
| Width (B) | Designed for common housing widths |
| Basic Dynamic Load Rating (C) | Calculated based on size and material; available upon request |
| Basic Static Load Rating (C0) | Provided for sizing calculations |
| Limiting Speed (Grease) | Applicable for standard industrial grease lubrication |
| Sealing Options | Open, single shield, or double shield configurations available |
| Lubrication Port Standard | Typically threaded for standard grease fittings |
Application Scenarios:
These bearings are well-suited for sectors where equipment operates under variable loads or in environments where installation precision is challenging. Common applications include:
- Agricultural Machinery: Tractors, harvesters, and conveyors subject to ground vibration and shock loads.
- Industrial Conveyors & Material Handling: Systems with long shafts or multiple support points.
- General Industrial Machinery: Fans, blowers, pumps, and light-duty gearboxes.
- Automotive Auxiliary Systems: Certain components in trucks and off-road vehicles.

Frequently Asked Questions (FAQ):
-
Q: What exactly does "self-aligning" mean for this bearing?
A: It refers to the bearing's internal design which allows the inner ring and ball set to tilt slightly relative to the outer ring. This compensates for small angular misalignments between the shaft and housing, preventing binding and excessive stress. -
Q: How does the lubrication port benefit me compared to a sealed bearing?
A: The port allows for periodic re-lubrication. In dusty, wet, or high-temperature environments, grease can degrade or leak. Re-lubrication refreshes the grease, extending service life beyond that of a permanently sealed bearing in such conditions. -
Q: Is carbon steel suitable for high-speed applications?
A: Carbon steel bearings offer reliable performance at moderate to high speeds common in industrial machinery. For extremely high-speed applications, material selection can be discussed based on specific requirements. -
Q: What is covered under the included warranty?
A: The warranty typically covers manufacturing defects and premature failure under normal operating conditions as defined in the warranty terms provided with the product. It is a commitment to our product's foundational quality. -
Q: Can you provide bearings with specific seals or coatings?
A: Yes. We offer various sealing options (open, shielded) and can discuss protective coatings or special tolerances based on your application's environment and performance needs. -
Q: What information do I need to provide to get a quotation?
A: Key details include: required inner diameter (d), outer diameter (D), width (B), expected load type and magnitude, operating speed, environmental conditions, and any preferred sealing or lubrication type. -
Q: Are your bearings compatible with standard housing designs?
A: Yes. Our bearings are manufactured to common industrial dimensional standards, ensuring compatibility with standard housing bore sizes and widths. -
Q: What is your typical lead time for production and delivery?
A: Lead times vary based on order quantity, customization, and current schedule. We strive for efficient turnaround and can provide estimated timelines upon receipt of your specific inquiry.
